I've suddenly developed tunnel carpel syndrome after brushcutting 2 acres
without anti-vibration gloves. I've lost feeling in my left thumb tip,index and middle finger,something called "white-finger". Any use of chainsaw,lawn mower or strimmer intensifies the numbness traveling up my left arm. This isn't a cry for sympathy (that's in the dictionary between sh*t and syphillus) this is a gentle prod towards you buying something that could save you a lot of grief in the future.
I would recommend the Stihl brushcutters and attach a blade (I have a three-pointed one for the size of the engine),don't bother with all that string,nylon or any other rubbish that takes ages to wind on,ages to unravel and an age to thread through little holes whilst wearing anti-vibration gloves,oh,and nice pretty sparks when ya hit granite too!!!
So go get some decent gloves,a decent harness and ear-plugs (or iPod at full blast
) and enjoy the zen-like art of clearing brush........ Ree
